WOOD-CHANNELING MACHINE.

SPECIFICATION forming part of Letters Patent No. 422,912, dated March11, 1890.

Application filed December 10, 1839. Serial No. 383,194. (No model.)

T0 (1% whom it may concern.-

Be it known that I, ALLAN B. CAMERON, of WVilliamsport, Lycoming county,Pennsylvania, have invented a new and useful Improvement inIVood-Ohanneling Machines, of which the following is a specification.

My invention relates to machines for making grooves or channelstransversely the surface of panels, 850., for the purpose of producingornamental patterns in intctglio or relief thereon; and it consists inthe combination,with a table and a rotary cutter operating through anopening in said table, of a guideplate to which the work to be channeledis attached and means, as more particularly hereinafter described,whereby said guideplate may be set and held in various positions, sothat said cutter may produce channels or grooves at various angles onthe surface of said work.

In the accompanying drawings, Figure 1 is a vertical section of themachine on the line X X of Fig. Fig. 2 is a top view of the guide-plateand fixed cross-bar entering the same. Fig. 3 is a vertical section onthe line Y Y of Fig. 1. Fig. 4 is a bottom View of the guide-plate,showing the work attached thereto.

Similar letters of reference indicate like parts.

A represents the table of the machine, having an upwardly projectingedge or side piece B.

Cis a shaft rotated by the belt-pulley D and supported in the standardof the machine and in a bearing E. The shaft 0 carries the cutter-headF, upon which are secured the cutting-knives G. These knives arefastened in place in the usual way by set-screws H, or in any othersuitable manner.

I is a fiat bar from which projects an arm J. At the end of the arm J iscarried the transverse metal bar K. The bar I rests against theupwardly-projecting ledge B of the table.

L is a guide-plate circularin form and provided at its upper side with aring M, in which are made numerous radial openings, as N, disposed atuniform distances apart. The ring M has a raised ledge or periphery O.The panel P to be channeled is fastened to the under side of the plate Lin any convenient way, and preferably by the clamps Q, which arefastened by screws R to the bottom of said plate. The plate is placedupon the table A with the panel to be cut downward and directly over theopening S in the table, in which opening the rotary cutter revolves.The' knives G project sufficiently above the upper surface of the tableto enter and act upon the under side of the panel. The cross-bar Kenters any two of the diametrically-opposite radial openings N and restsupon the plate L.

The parts being thus arranged, the operation of the machine is asfollows: The attendant grasps the bar J and moves it ina lateraldirection. (Indicated by the arrow in Fig. The bar I then slides alongthe ledge B and the plate L, carrying the work, moves over the rotarycutter. This movement takes place in a straight line, as the ledge B ofthe table acts as a guide. In this way a channel having a form orcross-section dependent upon the shape of the cutter-edge of the knife Gis produced transversely across the under surface of the panel P-such,for example, as shown at 1 2, Fig. 4. Assuming it to be desired toproduce upon the surface of the panel a pattern such as shown in Fig.at, the attendant now raises the bar J, and so lifts the bar K out ofthe recesses in the plate L. He then rotates said plate over an angle offorty-five degrees, and again drops the bar K into the recesses in thering M which comes immediately beneath it. The bar K will then assumethe position relatively to the plate indicated by the diagonal dottedline in Fig. 2. The plate is then carried over the cutter in the sameWay as before, when the channel 3 4 is produced on the panel. The sameoperation is again repeated, the plate being rotated over an angle offorty-five degrees, and in this Way the channel 5 6 is made, and in likemanner, after another partial rotation of the plate, a channel 7 Sisproduced, and thus the desired pattern is completed. Of course theextent to which the plate L is rotated will depend upon the patternwhich is sought to be produced, the machine making upon the surface ofthe panel more or less radial cuts, as may be desired, with greatcertainty and accuracy.

I claim 1. The combination of a table having an opening, a rotary cutterbelow said table and operating through said opening, a loose guide platehaving recesses on its upper side on said table, means for fastening theWork to be acted on by said cutter on the under side of said plate, anarm above said table and disposed at an angle to the plane of rotationof said cutter and provided With a projection constructed to enter arecess or recesses on said plate, and a leg or standard resting on saidtable, substantially as described.

2. The combination of a table having an opening, a rotary cutter belowsaid table and operating through said opening, a fixed guide bar orledge on said table and disposed in a plane parallel to the plane ofrotation of said cutter, a loose guide-plate having recesses on itsupper side on said table, means for fastening the Work to be acted on bysaid cutter 011 the under side of said plate, an arm above,

said table and provided with a projection at one end constructed toenter a recess or recesses in said plate, and at one extremity abar-disposed at right angles to said arm, the

said bar resting on said table and against said opening, guide-plate L,having recesses on one side, arm J, having bar K, constructed to enter arecess or recesses, and guide-bar I, said bar resting on said table andagainst said guide-ledge B, substantially as described.

4. The combination of the table A, having an opening S and guide-ledgeB, rotary cutter F below said table and operating through said opening,guide-plate L, having on its upper side the ring M, With radial recessesN, arm J, having bar K, constructed to enter diametrically-oppositerecesses N, and guidebar I, said bar resting on said table and againstthe guide-ledge B, substantially as described.
